The purpose of this report is to prepare a hazard risk assessment for one or more CBGs in the Bay Area. By making use of the ‘Our Coast Our Future’ website, an area of study was determined. For a scenario of 50cm sea level rise (SLR), and a 100 year return period (RP), a significant part of Foster City, California is at flood risk. For this reason, the northern zip code of Foster City (94404) was selected as the study region. The end goal will be to determine the average annualized loss (AAL) for vehicle damages in each census block within the Foster City zipcode between the years of 2020 and 2050.
First, the boundary for the selected zipcode in Foster City can be seen below.
From here, the TIF files were imported for several SLR (0cm, 25cm and 50cm), and RP (1 year, 20 year and 100 year) scenarios.
The flood maps for various RPs all within the 0cm SLR scenario for Foster City can be seen below:
